Angular impulse is defined as the product of the torque exerted on an object or rigid system and the time interval during which the torque is exerted. Angular impulse has the same direction as the torque imparting it. A rotational form of the impulse-momentum theorem relates the angular impulse delivered to a rigid system to the change in angular momentum of that rigid system.
